Tazawa] The different technical approaches are considered mostly to compare the accuracy attainable in microwaves to Far IR where new resonant tchniques have been developped. It is possible to use the fringes of the observed spectra to get directly the London penetration length. However in the present state of the Art there is more accuracy to use a two-fluid model with at least one Mid-IR oscillator, and a strategy is possible to fit separately the different parameters. The different results are reviewed and compared to the microwaves data. There is a good accordance, except perhaps for the power law-giving the concentration of quasiparticles in the superconductive phase. For a thin film of YBCO devoid of grain-boundaries (no twins), a θ4 law is found instead of a θ1.5 law for an ordinary film. It should be highly valuable that both microwaves and Far-IR data should be taken on the same sample.
